I couldn't get any clue. Could you please provide me a small VS solution together with source file? It might be easier if I can simply check the callstacks. BTW: please send me off-list if the file is too big. Thanks.

I personally haven't try to program MPI with MFC, but in principle it should work. What kind of error did you get, was there any error message? Thanks.

I have a MFC project, and need to add mpi functions in it,  and  choose openmpi.
but I  searched all of mail list ,  not. find the answer.

And I try to call mpi functions under MFC, as follows,

int ompi_test(int *argc, char **argv)
    int rank, size;

    MPI_Init(argc, &argv);
    MPI_Comm_rank(MPI_COMM_WORLD, &rank);
    MPI_Comm_size(MPI_COMM_WORLD, &size);
    printf("Hello, world, I am %d of %d\n", rank, size);

    return 0;
void CSchedulerDlg::OnBnClickedButton1()
    ompi_test(NULL, NULL);

but break at MPI_Init(argc, &argv);.

So what should I do?
Can anybody help me?

Thanks in advance.

Best Regards.
